Abstract
A camera including a combined shutter and adjustable aperture is characterized by resilient means for uniformly dampening oscillations during operation. The combined shutter and aperture includes a stepper motor that drives a plurality of blades between a closed aperture blocking position and a plurality of open aperture defining positions. The blades and stepper motor are coupled by a drive train that increases friction in the drive train uniformly in all positions of the blades. A counter weight is provided for balancing inertial forces on said ring.
